1 MITSUBISHI ELECTRIC RESEARCH LABORATORIES GaN PA for 4G LTE-Advanced and 5G Ma, R.; Teo, K.H.; Shinjo, S.; Yamanaka, K.; Asbeck, P. TR October 2017 Abstract This paper reviews the state-of-the-art of RF power amplifiers technologies in cellular base station for 4G and coming 5G mobile wireless communications. GaN device technologies enable various advanced power amplifiers architectures to offer high efficiency, and high power applications for wide band signal transmission. It summarize the system-level requirement posed by 5G new radios and outlooks the potential challenges and opportunities of advanced GaN PA developments.
